game maker pixel art resolution



in my project.... I want my graphics to use pixel art. but it doesn't look so good, sometimes the pixels don't even appear, and when i reduce the view size to zoom in ,it appears to be smudged. i use 32x32 sprite resolution and i remember this didn't used to happen in my previous game maker please will anyone give me any advice or tips about what i am doing wrong. your help would be appreciated.
